Answer:
216 US dollars
Step-by-step explanation:
Let the amount he earned for babysitting be x
He spent 1/4 of x on guitar=(1/4)×x=1/4x
He gave 1/4 of x to charity= (1/4)×x=1/4x
Equation 1
Total amount left=(Total amount earned -Total amount spent)
Total amount earned=x
Total amount spent=(Spent on Guitar+Spent on Charity)=(1/4x)+(1/4x)=1/2x=0.5x
Total amount left=108 US dollars
Substituting in equation 1
108=(x-0,5x)
Solving
0.5x/0.5=108/0.5
x=216 US dollars
He started with 216 US dollars
1 meter = 0.001 kilometers. This should help you find the answer.
Answer:
Step-by-step explanation:
Since all the angles of triangle add up to 180 degrees,
Missing angle +100 +43=180.
Let the missing angle be 'x'.
Then, x + 100 +43 =180
or, x + 143 = 180
or, x = 180 - 143 = 37 degrees
So, the next angle is 37 degrees
The tots of two numbers, or you know the communitive property
We know that
[lateral area]=perimeter of the base*height
perimeter of the base=10+24+26-----> 60 cm
height=26 cm
[lateral area]=60*26-----> 1560 cm²
the answer is
the option A) 1560 cm²
